Single-phase of BaFe12-xNbxO19 (x ≤ 0.1) hexaferrite (HFs) were fabricated via citrate sol-gel route. The Ba hexaferrite formation has been confirmed by XRD and FE-SEM. The conductivity and dielectric properties of some Nb3+ions-substituted BaFe12O19 hexaferrites (Ba-HFs) were studied extensively via impedance spectroscopy. Some important parameters; dielectric constant, conductivity, dielectric loss, complex modulus and dissipation factors were analyzed at temperatures up to 120 °C in 1.0 Hz to 3.0 MHz in frequency interval for various Nb substituents.
